The family’s statement Tuesday didn’t disclose a deal price, but said the deal will include cash plus units that provide Carlyle with a continuing financial interest.

Hellman & Friedman LLC took the company private in 2008 for about $2.4 billion, including debt. In a 2012 deal valued at about $3.3 billion, Carlyle bought a controlling stake. Co-founder Mark Getty and the Getty family rolled over substantially all of their ownership interests, while management invested equity.

Getty Images, founded in 1995, has long served the media and advertising industries. In September 2014, it launched its first consumer app, Getty Images Stream.

Over the years the company expanded beyond photos into video and music with moves like the 2007 purchase of music-rights business Pump Audio for $42 million. The company has licensing deals with technology companies including
Microsoft Corp.

According to Moody’s, Getty Images had revenue of about $836.8 million for the 12 months ended Sept. 30, 2017.

The Getty family said Tuesday that the transaction is expected to close by the end of the third quarter.
